Effective Methods of Restraining Diffusion in Terms of Epidemic Dynamics

Abstract Removing influential nodes or shortcuts in a network restrains epidemic or information diffusion, but this method destroys the connectivity of the network and changes the topological structure. As an alternative, an additional field can be imposed in the network to affect node behaviors and...
